Unexpected non-whitespace character after JSON at position 10243

[hse00435-hub]

Bug Description

I am a paid subscriber. When using the web platform, clicking "Start Engine" consistently triggers a red error message: Unexpected non-whitespace character after JSON at position 10243.

This happens regardless of the file type uploaded (I have tested with clean English .txt files, standard .pdf files, and various simple texts). The error code position 10243 remains identical every single time, which seems like a backend parsing or cache lock issue related to paid account status API.

Steps to Reproduce

1. Log into a paid account.
2. Upload any valid text/PDF file into "01 / REALITY SEEDS".
3. Enter any simple prompt in "02 / SIMULATION PROMPT".
4. Click "Start Engine".

Expected Behavior

The simulation should start, and the sequence light "01 / Ontology Generation" should activate.

Actual Behavior

The system completely locks up and throws the JSON position 10243 error immediately. Cleared browser cache and force-refreshed (Ctrl+F5) multiple times, but the error persists. Please investigate as this severely affects paid users.

A fix for this is up in #626 — adds a 5-stage robust LLM JSON parser (_parse_llm_json) that handles the trailing-prose pattern that's causing the strict json.loads to fail. 8/8 unit tests pass, including the exact position 10243 pattern. PR: #626

Thanks for the quick patch in #626! However, please note that the live production website is STILL throwing the exact same error (as shown in my newly uploaded screenshot).

It seems the fix has been coded and passed your local unit tests, but it hasn't been merged or deployed to the live production server yet. Paid users are still completely blocked by this position 10243 bug on the web platform.

Could you please nudge the team to deploy PR #626 to the production server ASAP? Thank you!
